Tofcll whom timayocmcem l Be it known that we, CHARLES L. BASTIAN and HJALMAR lVIA'IHIsnN,` citizens of Athe United States, residin at` Chicago, in `the countyof Cookand tate of Illinois, have invented certain new andluseful Improvements in Combination DraftfArms, of which the `following is a specification. l

This invention relates to dispensing devices `forcarbonated` bevera es but more particularly `to combination raft arms or faucets for controlling the discharge of syrup `and carbonated water.

The primary object of the invention isto provide a draft arm which is simple, `and durable in cons truction and may be quickly7 and easily operated.

Further objects of the invention `are to provide an improved valve construction for controlling the lilowofsyrup to and from a l measuring chamber, to provide means for shutting off the supply of syrup independently of the Water, and to prevent leakage `of the syrup. v o l 1 l The many other objects and advantages of the invention will` `be `better understood by reference to the following specification when read in connection `Withthe accompanying drawings illustr ting a selected en1 bodimentzthereofuin whichr` Figure 1 is a central vertical section of my o invention; and

Fig. 2 is a section on `the line 2, 2 of Fig. 1. I n the drawing my improved draft` arm comprises a casing 5 mounted at 6 on the usual standard through Which the carbonated water is admitted to the draft arm. This casing 5 is provided with a discharge nozzle 7 of the usual tylpe. A cylindrical casing 8 is mounted on t e upper portion of the casing 5 to support the syrup supply reservoir 9, and form a conduit for the syrup therefrom. A measuring chamber 10 within the casing 8 and spaced therefrom has its lower threaded end 11 seated Vin the upper wall of the casing and the interior Wall of this chamber 10 is preferably threadedto receive the correspondingly threaded head of an adjusting plunger 12 provided with operating stem 13.

A valve chamber 14 is provided Within the casing 5 to contain and form a seat for the rotary valve 15 which controls the flow of the syrup from the reservoir 9 to the measl Specification of Letterslateiit.

` uring chamber l0 and from this chamber to the dischar e nozzle 7. The valve 15 is cylindrical 1n form and is provided with a i passage 23 extends through the valve 22 and is adapted to register with oppositely disposed passages 24 in the valve 15. The passages' 24 communicate with one end of the channel 18. The valve 22 has a stem 25 extending through the stem 16 of the valve 15 and an operating handle 26 is secured upon the outer extremity of this stem. y

A discharge passage 27 in the casing 5 connects the chamber 14 with the nozzle 7. A perforated washer or packing ring fits in the mouth of this passage and is pressed firmly against the face of the valve 15 by the gland 29 to prevent leakage of the syrup.

The carbonated Water enters the casing 5 through the inlet passage 3() which is preferably provided with a pressure regulator 31 to permit adjustment of the draft arm for varying Water pressures. The valve 32 and the parts operating in conjunction therewith to control the flow of the Water to the nozzle 7 form no part of the present invention and further description is considered unnecessary. An arched operating yoke 17 joins the stems of the valves 15 and 32 so that these valves are operated simultaneously by the handle 17 In the operation of the draft arm the yoke 17 normally rests in its raised position as indicated in the drawing. The channel 18 in this position communicates with the passages 19 and 20 and permits flow of syrup from the reservoir to the measuring cham ber. The capacity of this chamber depends upon the position of the adjusting plunger therein. This plunger should be set to provide uniformly the charge of syrup desired. To discharge the syrup contained in the measuring chamber the valve 15 is rotated by the handle 17 until the passages 20, 23, 24 and 27 are in registration. The rotation passage 23 out of registration with the passage 24. The yoke 17 may now be raised to Aoperate the valve 32 but no syrup is released from the measuring chamber.

Thisv draft arm is exceedingly simple and durable inconstruetion and may be quickly and easilyfoperated. The rotary valve simplifies both the construction and the operation.l Valves in draft arms'are subjected constantly to sticky syrups which tend to cake uponthem and prevent proper seating so thatleakage'of syrup quite generally occurs. VThe present valve is always in rm contact with its vseat'so that the contacting surfaces formfa Vprotection for eachother andthereis practically no opportunity for the Acollection of deposits. The supplementary control Vfor` the syrup vsupply ens,

ables syrup and water to be drawn simultaneously or Water to be drawn Without syrup. The 'entire devicehas few parts and these may easily be disassembled and cleaned.

We are aware that many changes in construction and 1n arrangement of parts may be made Wlthout departing from the invention and We reserve the right to make all suchV changes as fairly yfall Within the scope of the following claims.`

TWe claim:

1. A dispensing device for liquids comprising a casing, a valve chamber in said casing, a Huid supply reservoir communieating with said chamber, a measuring receptacle communicating With said chamber, a discharge passage leading from said chamber, and a rotary cylindrical valve member in said chamber provided with a passage therein to establish communication between said reservoir and said receptacle in one position of said member and between said receptacle and said discharge passage in another position of said member.

i dispensing device for liquids comprising a casing, a valve chamber in said casing, a measuring receptacle connected by a passage with said chamber, a discharge passage from said chamber, a rotary valve having a passage therethrough to register lwith said passages to establish communication between said receptacle and said dis` charge passage, and means operable independently of said rotary valve to cut o said communication when said passages are in registration.

3. A dispensing device for liquids comprising a casing, a valve chamber in said casing, a measuring chamber connected by a passage with said valve chamber, a discharge passage from said valve chamber, a rotary valve having a passage therethrough to register with said passages to establish communication between said measuring chamber and said discharge passage, and a second rotary valve Within the iirst mentioned valve and operable independently thereof to cut off said communication when said passages are in registration.
